Yes, FL-Blend is an alternative variation of the FL-41 tint. By filtering out the most harmful wavelengths of light between 480-520nm with a softer plum tint, FL-Blend offers a truer color experience while still helping manage light sensitivity.

As a result of reducing exposure to this problematic light, FL-Blend may also help people to live well with migraine as part of an overall light management plan.

Yes, our FL-Blend lenses filter light between 480-520nm, which is in the blue-green spectrum. They also remove more wavelengths across a wide spectrum of blue light than typical clear or nearly-clear blue light glasses.

Like all TheraSpecs lenses, FL-Blend also blocks 100% UV light and features an anti-reflective coating to further enhance your comfort.

FL-Blend is best if you have mild or moderate light sensitivity and/or if you want a more subtle lens option to fight against artificial light, such as computer and device screens, fluorescent lights, and LEDs.

FL-Blend targets the same wavelengths as FL-Pro with a softer, plum-colored lens. This means it trades some of the strength found in FL-Pro for a more subtle tint with less noticeable color change. If you want the strongest defense against artificial light or have more severe light sensitivity, we recommend starting with FL-Pro.

In addition, FL-Blend is available in two lens strengths, whereas FL-Pro offers three strengths, all of which can help meet your specific needs.

FL-Blend is part of our FL-41 lens family. These lenses use the same core tint but vary in strength and intended use. We also offer other lens options that target different parts of the light spectrum, so here’s how FL-Blend compares to all of our lenses:

Yes, FL-Blend is available in multiple tint strengths. The right option depends on your level of light sensitivity and how much filtering you need. Higher strengths provide more filtering for stronger or more frequent sensitivity. Here are the different strengths of FL-Blend:

FL-Blend (Standard)

FL-Blend (Extra)

If you’re not sure where to start, our lens assistant can help guide you based on your environment and preferences.

You can wear FL-Blend lenses indoors, as they are designed for protection against screens and other artificial light. They can be worn outdoors and provide full UV protection, but for brighter conditions or stronger sunlight sensitivity, many customers prefer FL-Sun lenses.

FL-Blend (all strengths) is too dark to be legal for nighttime driving, so Flex or Contrast HEV lenses are recommended instead.

Yes, you can get FL-Blend lenses with your prescription or with reader correction. (Note: WearOver styles are non-prescription only.) Simply tap/click on your preferred frame style above, choose either "Prescription" or "Reading Glasses" under Lens Correction, and complete the rest of the options before adding to your cart.

You have 60 days for returns or exchanges of all non-custom TheraSpecs, so you can make sure FL-Blend is the best option for your needs. If you are wanting prescription or reader TheraSpecs, we suggest starting with one of our fully refundable fitover styles.
